It has excellent transformer oil impregnation feature, high compressive strength more than corrugated pressboard which is the old technology. It is used at high temperature condition and it could be improved the circuit strength.The character are below:1. High mechanic strength2. High electric strength3. Accurate dimensionApplication: Oil duct strip provides duct for the flow of the cooling oil in layer and strip windings in distribution power transformers. It is manufactured by bonding transformer board sticks onto insulating paper or single-coated diamond dotted paper.Main strips: Rectangular strips, T-strips, Pigeon cauda strips, Abnormity strips.TRANSFORMER OIL DUCT STRIP DATA SHEETPART1: PRESSBOARD STICK4*5*1000MMITEMTYPICAL VALUESMATTER OF FACTThickness: mm4mm±7.5%4.1-4.3mm≤7.5%Width5±0.5mm4.95-5.38mm≤0.4mmLength of 1000mm:±5mm1000±3 mmPitch of stick centre:±3mm23±2 mmApparent density: g/cm31.1-1.21.18Moisture content ,%4.0 to 9.0%5.7PH water extract:6.0 to 9.06.8Ash content,% maximum1%0.51Tensile strength MpaMachine direction:Cross machine direction:≥90≥50107.4101.3Oil absorption≥7.0%12.29Shrinkage rate% MD CMD Thickness D≤1.0≤1.4≤6.00.160.25≤5Elongation rate MD CMD≥3≥4≥4.4≥4.4Conductivity of aqueous extract Ms/m≤10.05.03Dielectric breakdown:(Kv/mm)In AirIn Oil102416.735.7PART2: SINGLE SIDE DIAMOND DOTTED PAPER DATA SHEETITEMTYPICAL VALUESMATTER OF FACTCaliper: (millimeter)0.25mmThickness: mm0.25±0.025mm+0.060.260(0.260,0.258,0.262)Width: mm1000±5mm1000-1005Apparent density: g/cm30.9 to 1.11.01Moisture content ,%4.0 to 8.0%5.6PH water extract:6.0 to 8.07.5Ash content,% maximum1%0. 43Coating thickness per side mm0.006 to 0.0120.011Tensile strength,N/mm2Machine direction:Cross machine direction:803586.648.1Dielectric breakdown:(volts/layer ,dry test)≥21002230Bond strength: Kpa450kpa679Please Contact UsMiss:MonroeMob: 86-18526730325 Fax: 86-22-26664908 http://e.kangliyuankeji.com/
